Pressure-flow studies in the diagnosis of bladder outlet obstruction: a study comparing suprapubic and transurethral techniques.

Objective: To compare suprapubic and transurethral methods of measuring intravesical pressure in a group of men undergoing investigation for lower urinary tract symptoms (LUTS), to identify which urodynamic variables are affected by the presence of an urethral catheter during the voiding phase, and consequently whether there is any change in the grading of bladder outflow obstruction (BOO) using the commonly recognised grading systems.

Patients And Methods: Thirty-five men with LUTS underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure flow variables were measured in all patients with both methods, enabling calculation of obstruction using the commonly used grading systems, i.

Three-year followup of patients treated with lower energy microwave thermotherapy.

Purpose: A retrospective study was done to investigate the long-term outcome of patients treated with lower energy transurethral microwave thermotherapy.

Materials And Methods: A total of 305 patients with lower urinary tract symptoms and benign prostatic hypertrophy underwent transurethral microwave thermotherapy according to a similar protocol at 2 centers.

Results: After 3 years of followup 133 patients who had undergone transurethral microwave thermotherapy alone were available for study.

A 12-month study of the placebo effect in transurethral microwave thermotherapy.

Objective: To determine the placebo effect of transurethral microwave thermotherapy (TUMT) in the treatment of benign prostatic enlargement (BPE).

Patients And Methods: A prospective, randomized sham-controlled study in 93 patients (mean age 65, range 50-88) was conducted at two centres comparing TUMT or a sham treatment. Patients randomized to receive sham treatment underwent the same initial procedure as for TUMT, but the complete procedure was simulated on the visual display with no application of microwave energy.

Value of urine cytology in screening patients with prostatitis syndromes.

We reviewed the results of urine cytology examination of 206 patients with a diagnosis of prostatitis syndromes in the period 1985-1991. The urine samples showed an incidence of 20.4% for slight to moderate atypia and 6.

Diagnosis and treatment of 409 patients with prostatitis syndromes.

We reviewed 409 patients who had prostatitis syndromes during the period 1985-1991. Urine analysis, x-ray film of abdomen, and sonograms of the kidneys did not contribute to the diagnosis of prostatitis. In 22 percent of the urine samples, slight-to-moderate atypia was seen in urine cytology but no malignancy was found.
